I understand. You filed your 2020 return in January 2022 so it got filed on 2021 forms. That became your 2021 return. You need to AMEND that return to be for your real 2021 return. That may be tricky to do. You have to take out all the 2020 info and add in the 2021 info. Then you still need to file an original 2020 return.
